VPL Jail System’s documentation

The VPL-Jail-System serves as an execution sandbox used by the VPL plugin for Moodle. This sandbox provides a secure, interactive, and non-interactive execution of students’ code written in different programming languages. Non-interactive execution allows the testing and evaluation of the code.
